MILK-BOTTLE OPENER.

Application filed November 18, 1922.

T 0 all whom it may concern:

Be it known that we, Josnrrr FRANK Casino and ARTHUR BAIL, citizens of the United States, residing in the city of San Rafael, Marin County, and State of Cali fornia have invented a new and useful Improvement in a Milk-Bottle Opener, of which the following is a specification. 7

Our invention relates to improvements in bottle openers for removing the paper caps from milk bottles and the like.

The primary object of our invention is to provide an improved milk bottle opener.

Another object is to provide an improved device adapted to facilitate the removal of the cap from a bottle and to prevent the disturbance of the contents during such removal.

A further object is to provide an improved device arranged to engage the cap simultaneously upon opposite sides of the cap whereby the cap may be removed and replaced repeatedly.

A still further object is to provide a device which will normally remain in engagen'ient with the cap to cooperate therewith to close the bottle and prevent the en trance of foreign matter therein until the contents have been removed.

A further object is to provide an improved device of a simple and durable construction which may be manufactured at a nominal cost.

A still further object is to provide a device adapted to display a firm name for advertising purposes in connection with a device of daily household use.

We accomplish these and other objects by means of the device disclosed in the drawings forming a part of the present specification wherein like characters of reference are used to designate similar parts throughout said specification and drawings, and in which:

Fig. 1 is a broken sectional view of the top of a milk bottle disclosing the manner in which our improved opener is inserted into engagement with the cap.

Fig. 2 is a similar View showing the cap removing element rotated through ninety degrees into operative engagement with the cap, and also showing in dotted lines the manner in which the cap is lifted from the bottle.

Fig. 3 is a plan view of the opener as applied to the cap of a bottle.

Serial No. 601,825.

Fig. 1 is an enlarged side elevation of the opener partly in section showing the manner in which the piercing point is moved to en gage the inner side of the cap.

Referring to the drawings the numeral 1 is used to designate in general a member consisting of a handle portion provided with a piercing point 2 adapted fOr insertion through the papercap 3 of a milk bottle 4 or the like. The handle portion is preferably shaped from wire to form a ring such as may be readily grasped by an operator, one end of the wire being bent outwardly and shaped to form a spear shaped piercing point having shoulders 6 disposed within the plane defined iby'thering.v

A shank 7 connects the piercing point 2 with the handle portion 1, said shank being arranged to received a disc 8 slidably and rotatably mounted thereon. The disc 8 is preferably stamped from suitable sheet material and is provided with a pair of parallel ribs 9 stamped therein upon opposite sides of the shank 7. The disc 8 is preferably 30 made circular in shape'and of a diameter slightly greater than the narrowest portion of the neck of the bottle 1.

The operation of our device is as follows: The piercing point 2 is applied tothe approximate center of the cap 3 which is, tightly fitted into the mount of the bottle and is supported upon a shoulder 11. formed there. Sufficient pressure is then applied to force the point 2 through the cap, the disc 8 being thereby brought into contact with'the upper side of said cap. While the point 2 is being inserted through the cap. the disc is arranged in a position with the ribs 9 parallel to the plane defined by the member 1 so that when the point 2 is forced through the cap the handle portionwill be received between the ribs as shown in the-drawings. The handle portion is now rotated through an angle of approximately ninety degrees 1 to the position shown in Fig. 2 of the drawings and in dotted lines in Figs. 3 and 4, the shoulders 6 being thus moved to a position at right angles to the plane of entry. As. the handle portion is rotated the ribs 9 are engaged and the member 1 is moved outwardly with respect to the cap 3 and the disc 8 and the shoulders 6 moved. to engage the inner side of the cap and firmly press the same against the disc, the length of the shank 7 and the height of the ribs 11 being designed to afford the amount of movement tage as there is no possibility of any portion of the cap being forced into the neck of the bottle and a portion of the contents splashed out as commonly results from the prying forced applied with one of the openers now in common usage.

After removal of the cap from the bottle and the desired quantity of the contents removed, the cap may be readily returned to its seat upon the shoulder 11 as the disc 8 permits a uniform pressure to be applied upon the cap which will force the cap into closing position without mutilating or bending the cap. The opener is preferably allowed to remain attached to the cap so that the cap may be removed and replaced repeatedly until the contents of the bottle have been exhausted the clamping of the cap between the shoulders 6 and the disc 8 permitting an indefinite number of removals and replacements without damage to the cap itself.

The disc is easily stamped from sheet metal or other suitable material and the ribs 9 stamped thereon at a single operation. In this connection it should also be noted that the disc 8 may also be stamped with the name of a dairy or other organization to whom the display of the name in such a conspicuous manner on an article of daily usage may be of advertising value. This feature of the device is of commercial importance because of the fact that the device can be made so cheaply as to afford a ready and extensive market to firms interested in the free distribution of advertising novelties.

As above stated the disc is made of a diameter slightly greater than the least diameter of the neck of the bottle, in this manner affording a larger area of engagement with the cap and preventing the inadvertent dropping of the opener into the bottle.

From the above description it will be seen that we have provided an improved device which will materially facilitate the removal of the cap from the bottle and which will combine with the cap to form a cover readily applied to the bottle for closing the same to maintain the contents in a clean and sanitary condition. 7

Having thus described our invention what we claim as new and desire to secure by Letters Patent is:

1. A milk bottle opener comprising a member having a spear shaped point adapted for insertion through the cap of milk bottles and the like; shoulders formed upon F the piercing point arranged to engage the inner side of the cap whereby the cap may be removed from the bottle; a disc slidably and rotatably mounted upon the member above the piercing point to engage the upper side of the cap for returning said cap to the bottle; and ribs formed upon the discto engage and move the member outwardly with respect to the cap when rotated from the entering position whereby the shoulders may be moved into firm engagement with the cap. 7

2. A milk bottle opener comprising a member having a piercing point adapted for insertion through the cap of milk bottles and the like, said member havinga handle portion arranged opposite the piercing point; a disc slidably and rotatably mounted upon the men'iber between the point and the handle portion; shoulders formed upon the point and arranged to engage the inner side of the cap; andribs formed upon the disc upon opposite sides of the member to engage the handle portion and cause an out ward movement thereof when rotated from an entering position whereby the shoulders are moved to press the cap firmly against the disc. I

A milk bottle opener comprising a member having a spear shaped piercing point provided with shoulders adapted to engage the inner side of the cap of'milk bottles and the like when inserted there-- through; and a disc mounted upon the inemher to engage the cap upon the outer side thereof; and a pair of parallel ribs formed upon the disc upon opposite sides of the member, said ribs being arranged to engage the member and cause an outward movement thereof when said member is rotated relative to the disc and the cap whereby the shoulders of the piercing point are moved to engage the cap and compress the same against the disc as and for the purposes described.

In witness whereof we hereunto set our signatures.
